I am making a 12x18 sheet cake for a friend's daughter's b-day tomorrow. I wanted to make the cake today because I have not yet made one this big and I am putting a fbct on it and an edible image. If I make the whole cake today (including putting the edible picture on) will it be okay refrigerated until tomorrow?

Your cake will be fine. I have done this quite a few times, no problem. I would just wrap in very well in saran wrap to keep it from drying out. Good luck!

It will be fine!! Just make sure you seal the cake good with your icing.

Ok, I'm a dork!! I completely missed the part about putting the image on today! I WOULD NOT wrap in tightly in saran wrap! Sorry about that. Just like ashleymomx2 said, make sure you seal the cake with your icing! SOOO sorry about that!!

I have left cakes boxed sitting overnight and they are perfectly fine. If you need to cover it an upside down laundry hamper or large box works great.

The edible image will be fine if you keep the cake covered and refrigerated. I always refrigerate my edible image cakes in the warmer months cause left out at room temp overnight or longer and the images can become really shiny or even bubble. I put mine in a cake box and then cover the box with plastic wrap.

My cake teacher told us that a completely iced cake will stay fresh for 3 days. Good luck!

I never wrap my cakes after they are decorated. And I do not put them in the fridge either. If they are sealed well with icing, they will last just fine.
